HIGH SPEED STEEL (HSS)

Our High Speed Steels are high-performance special steels combining high toughness and high hardness levels, thanks to susbstantial proportions of elements like tungsten, molybdenum, vanadium and chromium which are able to form carbides. To improve hot hardness, cobalt may also be added.

Here are a few advantanges of our High Speed Steels:

Excellent tenacity ensuring good resistance to impacts and vibrations: this is imperative for the manufacture of dependable cutting tools.

Great wear resistance thanks to a carefully chosen degree of hardness.

Cutting edges with ideal sharpness to guarantee the finest productivity.

Thanks to the powder-metallurgy process, higher-quality products can be obtained, offering the following advantages :

A higher hardness, due to a higher content of carbide-forming elements

A higher toughness, because the material is free from carbide segregation. In addition, the ESH process removes about 90% of non-metallic inclusions, ensuring better reliability of powder-metallurgy HSS tools

Isotropic properties, because the material exposes a structure with an even distribution of carbide particles in the matrix phase, in contrast to ingot cast high speed steels where carbides tend to form lines during transformation
